Abstract

본 발명은 로렌쯔 카오스 발생회로 및 이를 이용한 음성비화 통신시스템에 관한 것으로, 본 발명에 의한 음성비화 통신시스템은 전송부는 음성신호를 소정의 신호에 의하여 암호화하여 전송하고, 수신부는 상기 전송부로부터 전송된 신호로부터 원래의 음성신호로 복원하는 음성비화 통신시스템에 있어서, 상기 전송부는 카오스시스템의 구동 부시스템에서 음성신호를 카오스신호와 합성하여 전송하고, 상기 수신부는 카오스시스템의 응답 부시스템에서 카오스 동기화를 수행하고, 상기 전송부로부터 전송된 신호에서 카오스신호를 빼내어 음성신호를 복원함을 특징으로 한다.The present invention relates to a Lorentz chaotic generation circuit and a voice communication system using the same. In the voice communication system according to the present invention, a transmission unit encrypts and transmits a voice signal by a predetermined signal, and a reception unit is transmitted from the transmission unit. In a voice communication system for restoring an original voice signal from a signal, the transmitter transmits a voice signal synthesized with a chaos signal in a driving sub system of a chaos system, and the receiver performs chaotic synchronization in a response sub system of a chaos system. And extracting the chaotic signal from the signal transmitted from the transmitter to restore the voice signal.

발명에 의한 음성비화시스템은 예측이 불가능한 카오스신호를 이용하여 하드웨어적으로 비밀통신이 즉각적으로 이루어지므로, 암호 및 복원의 속도도 빠르며 시스템의 크기와 가격면에도 효과적이다. 따라서 일반적인 전화기와의 연결이 가능하다.The voice speech system according to the present invention uses a non-predictable chaos signal so that the secret communication is instantaneously in hardware. Therefore, the encryption and restoration speed is fast, and the size and price of the system are effective. Therefore, it is possible to connect with a general telephone.
